   ...CRITICAL FIRE WEATHER AREA FOR EASTERN WY/SOUTHEAST MT/FAR
   SOUTHWEST ND/WESTERN SD/WESTERN NEB...
   
   ...SYNOPSIS...
   WITH BROAD UPPER RIDGE ACROSS THE SOUTHERN STATES...AN ACTIVE/FAST
   BELT OF WESTERLY MID TO UPPER FLOW WILL REMAIN ACROSS THE NORTHERN
   THIRD OF THE COUNTRY. WITHIN THIS FLOW REGIME...A POTENT SHORTWAVE
   TROUGH/ASSOCIATED COLD FRONT WILL CROSS THE NORTHERN PLAINS TODAY.
   IN THE WAKE OF THE INITIAL SYSTEM...A SECONDARY UPPER IMPULSE WILL
   SHIFT EAST-SOUTHEAST OVER THE PACIFIC NORTHWEST/NORTHERN
   INTERMOUNTAIN WEST.
   
   ...CRITICAL FIRE WEATHER AREA - EASTERN WY/SOUTHEAST MT/FAR
   SOUTHWEST ND/WESTERN SD/WESTERN NEB...
   
   PRIMARY CONDITIONS: STRONG WINDS/WIND SHIFT WITH COLD FRONTAL
   PASSAGE
   
   A POTENT SHORTWAVE TROUGH AND AN ASSOCIATED COLD FRONT WILL PUSH
   EAST FROM THE NORTHERN ROCKIES ACROSS THE NORTHERN PLAINS TODAY.
   ASSOCIATED WITH THE COLD FRONT...A WIND SHIFT IS EXPECTED BY EARLY
   AFTERNOON INTO THE WESTERN DAKOTAS/NEB PANHANDLE...WITH A MARKED
   INCREASE OF NORTHWESTLY WINDS VIA STRONG MOMENTUM TRANSFER/CORE OF
   MODERATELY STRONG WINDS ALOFT. SUSTAINED WIND SPEEDS OF 20-30
   MPH...WITH GUSTS TO 40 MPH...MAY HAVE CONSIDERABLE ADVERSE IMPACTS
   ON ANY ONGOING FIRES /NAMELY ACROSS MT AND WY/. GIVEN THE MAGNITUDE
   OF THE WINDS...POTENTIAL WILL EXIST FOR FAST FIRE SPREAD EVEN WITH
   THE ONSET OF COOLER TEMPERATURES/HIGHER RH VALUES AMIDST THE
   POST-FRONTAL REGIME. IN ADDITION...ISOLATED-SCATTERED THUNDERSTORMS
   WILL BE POSSIBLE PRIMARILY ALONG THE FRONT. WHILE THESE SHOULD BE
   MAINLY WET...POTENTIAL WILL EXIST FOR NEW FIRE IGNITIONS.
   
   ...GREAT BASIN...
   ON THE HEELS OF THE INITIAL SHORTWAVE TROUGH/COLD FRONT SHIFTING
   EAST ACROSS THE NORTHERN ROCKIES/NORTHERN PLAINS...A SECONDARY UPPER
   TROUGH WILL EVOLVE OVER THE PACIFIC NORTHWEST/NORTHERN INTERMOUNTAIN
   REGION TODAY. THIS PATTERN WILL KEEP A PERSISTENT BELT OF MODERATELY
   STRONG WINDS OVER THE NORTHERN GREAT BASIN...FAVORABLE FOR BREEZY
   CONDITIONS ACROSS MUCH OF NV THIS AFTERNOON IN PRESENCE OF
   SUFFICIENTLY DEEP MIXING. BROAD SCALE WINDS OF 15-20 MPH ARE LIKELY
   THIS AFTERNOON...WITH GUSTS TO 30-35 MPH. OTHERWISE...WARM/DRY
   CONDITIONS WILL CONTINUE WITH AFTERNOON MINIMUM RH VALUES BETWEEN
   8-12 PERCENT.
